Food Misconceptions – Fruit or Vegetable?

Today I thought I would write about some of the more common food misconceptions. By this I mean incorrect references to some foods, particularly in regards to whether something is a fruit or vegetable. I was talking with some colleagues about this this week and I thought it would be interesting to research and share.

First – Peanuts

Many people regards peanuts as nuts, however they are not. As per Wikipedia – ‘The peanut, also known as the groundnut and the goober and taxonomically classified as Arachis hypogaea, is a legume crop grown mainly for its edible seeds.’ ‘The botanical definition of a “nut” is a fruit whose ovary wall becomes very hard at maturity. Using this criterion, the peanut is not a true nut, but rather a legume. However, for culinary purposes and in common English language usage, peanuts are usually referred to as nuts.’ I’ve often wondered if that is the reason I don’t like them. I like all the other nuts!

Next – fruits and vegetables

Vegetable According to Dictionary.com a vegetable is any plant whose fruit, seeds, roots, tubers, bulbs, stems, leaves, or flower parts are used as food, Fruit Dictionary.com states that fruit is the developed ovary of a seed plant with its contents and accessory parts. Including the edible part of a plant developed from a flower, with any accessory tissues, Using this more specific definition all fruits are considered vegetables but not all vegetables are fruit. Olives, plums, tomatoes, artichokes and cucumbers are fruit. Lettuce, potatoes, celery and beets are not reproductive parts of the plant developed from flowers so are considered vegetables. So with that in mind, a tomato is not a vegetable. Neither is corn, zucchini, pumpkin, green beans and peas. Interestingly, berries are fruits that come from a single plant ovary with multiple seeds. With this in mind, scientifically bananas, grapes and capsicum are actually berries.
More berry facts
Raspberries, blackberries and mulberries are called ‘Aggregate fruits’ because they are actually a bunch of tiny little fruits grown together. Strawberries are also a different kind of fruit called a ‘fleshy receptacle’. This is because the actual fruits are the tiny little seeds stuck to the outside of the strawberry. Wow, who would have thought that there were so many fruits and vegetables that we refer to incorrectly. I will be looking at my fruit and veges in a whole new light now.

What is the Glycemic Index?

Hi, today I’m going to talk about the ‘Glycemic Index’ and food.

Every food we eat affects our body differently, and not just in terms of health. The way it is processed by the body affects our energy and blood sugar levels.

Scott is studying Nutrition this semester and has been learning all about the ‘Glycemic Index’. He shared some facts that I found very interesting and I decided to share them with you.

First of all, what is the ‘Glycemic Index’?

Wikipedia states –‘The glycemic index (GI) is a number associated with the carbohydrates in a particular type of food that indicates the effect of these carbohydrates on a person’s blood glucose (also called blood sugar) level.’….’ The GI represents the rise in a person’s blood sugar level two hours after consumption of the food.’

In basic terms – foods that are difficult for the body to digest are considered Lower GI foods usually with a value (55 or less). These foods cause a lower and slower rise in blood glucose and, therefore, insulin levels.

What about ‘Glycemic Load’?

Another method of measuring the effect of food on the body’s glucose is considering its ‘Glycemic Load’ (GL).

GI does not consider the portion of food, but glycemic load (GL) does.

Basically, if a food is ranked high on the glycemic index it has readily available carbohydrate for quick absorption. However, the same food can have a low glycemic load because there may not actually be much total carbohydrate in a given serving of that food. A low GL is the better indicator that a food won’t have much impact on blood glucose levels.

The difference

Here are two examples: Watermelon has a high GI of 72, yet a low GL of 7.21. The high GI is based on 5 cups of watermelon, not an actual serving size of 1 cup. The low GL means one serving of watermelon doesn’t contain much carbohydrate, because it is actually mostly water. The low GL indicates that a serving of watermelon won’t have much impact on your blood sugar.

Carrots are another example of a low GL food that many people think will raise their blood sugar a lot — but it’s not true. That’s because carrots have a high GI of 71. However, what most people don’t know is that the GL for carrots is only 6. 

Therefore, unless you’re going to eat half a kg of carrots in one sitting, an average serving of carrots will have very little impact on blood glucose levels. That said, juicing carrots — which means consuming more carrots at once — will have a greater impact on blood glucose.

With this in mind, here is an interesting fact that Scott has shared in regards to potatoes.

Potatoes are generally regarded as having a high GI rating, because they are a simple starch food, which is quickly converted into sugar. However it is possible to alter this.

By cooking potatoes, then cooling and again reheating them, the starches become ‘resistant’. This means that they now resist digestion and so in this way are considered a low GI food.

 

I hope this information has helped you to have a better understanding of these terms that are so often used to describe the food we eat.

Holidays and Excess

For the past two weeks Scott and I have been on holidays with friends. It was a lovely break, full of fun, food, fresh air and sunshine, with no housework or cooking.

We went for a cruise around New Zealand. Our stops included some lovely seaside towns where we walked many kilometres. Both of us are fans of the ‘Lord of the Rings’ movies, so we also went on some movie tours. Visiting filming locations and the special effects studio, which were amazing!

We treated ourselves to a few lovely New Zealand ice creams along the way.

The challenge,

Cruising also includes great entertainment with plenty of fabulous food and indulgent drinks. It can be quite a challenge for some to limit their intake, as there is so much choice on offer. We worked out that there was food on offer for almost 20 hours each day.

As with most holidays, it is a time of relaxation, so it is difficult to find the motivation to maintain some type of fitness or exercise routine.

Scott and I decided that one way to keep up some form of exercise was to always use the stairs. As our room was located on level 5 and many times we were going to level 14, we climbed many stairs. 140 each time, to be exact.

Many of my regular readers are aware that Scott and I decided some time ago to adopt a healthier lifestyle. We decided to do this by eating more whole foods and reducing our exposure to chemicals. Always with the 85 to 90% rule in mind, this allows a small allowance for treats and occasional eating out.

We definitely used up our 15% of excess!

On a cruise it is difficult to avoid chemical exposure, especially with the hand sanitiser you are expected to use before entering any restaurant. The food is also plentiful and very tasty, so there was quite a digression from our usual diet. That is, however, what holidays are all about.

The plan moving forward,

With the return to our normal routine, it’s time to “pay the tax” so to speak and detox. For us that means a mostly plant based diet with no alcohol. Increasing our daily exercise will also help to burn off those extra ‘cruise kilos’.

I think it’s important for our mental health to ‘let loose’ and be indulgent when on holidays. However, for our physical wellbeing, it’s important to return to a healthier type of routine when the holiday ends.
